The present study seeks to find the effect of oral health status that parents recognized, oral health habit and food intake on existence of decalcified teeth and decayed teeth. Participants were 293 infants aged 18-24 months who visited C dental clinic in Kyungki province between January and December 2010. Questionnaires and oral exam results were used and statistically analyzed by the SPSS program. Fisher's Exact and chi-square test were used to analyze the data. The 18-20 month-old age group had the highest rate of decalcified teeth with 36.4% while the 23-24 month-old age group had the highest rate of decayed teeth with 37.0%. Bottle feeding showed correlation with decalcified teeth, and decayed teeth. Parents were able to recognize decayed teeth and decalcified teeth. Group 2 food(soda/soft drinks/sugared fruit juice) was related to decalcified teeth and decayed teeth(p<.001). Group 4 food (cake/cookies/doughnut/dried fruit/banana) and group 5food(caramel/candy/chocolate bar) were both related to decalcified teeth(p<.001). As the result of dental examination, dental treatment was highly needed for the 21-22 month-old age group(89.3%), and preventive treatment and plaque control were highly needed for the 18-20 month-old age group(94.5%). The results concluded that 18-24 months was the critical period for children's oral health, therefore organized oral health education for parents is necessary.
In this paper, we analysed RSS characteristics by external factors and presented an efficient algorithm for real-time location tracking and its hardware system. The proposed algorithm enhanced the ranging accuracy using Kalman Filter based on the RSS DB. The location tracking system that consists of the tag, AP(Access Point), a data collector(Data Receiver) with IEEE 802.15.4(ZigBee) network environment, and location tracking application that reveal locations of each tag is implemented for the test environment. The location tracking system presented in this paper is implemented with MSP430 microprocessor manufactured by TI(Texas Instrument), CC2420 RF chipset and the location tracking application. With the results of the experiment, the proposed algorithm and the system can achieve the efficiency and the accuracy of location tracking with the average error of 19.12cm, and its standard deviation of 5.31cm in outdoor circumstance. Also, the experimental result shows that exact tracking of position in indoor circumstance cannot achieve because of vulnerable RSS with external circumstance.
Although genetic markers identifying women at an increased risk of developing breast cancer exist, the majority of inherited risk factors remain elusive. Mutations in the BRCA1/BRCA2 gene confer a substantial increase in breast cancer risk, yet routine clinical genetic screening is limited to the coding regions and intronexon boundaries, precluding the identification of mutations in noncoding and untranslated regions. Because 3' untranslated region (3'UTR) polymorphisms disrupting microRNA (miRNA) binding can be functional and can act as genetic markers of cancer risk, we aimed to determine genetic variation in the 3'UTR of BRCA1/BRCA2 in familial and early-onset breast cancer patients with and without mutations in the coding regions of BRCA1/BRCA2 and to identify specific 3'UTR variants that may be risk factors for cancer development. The 3'UTRs of the BRCA1 and BRCA2 genes were screened by heteroduplex analysis and DNA sequencing in 100 patients from 46 BRCA1/2 families, 54 non-BRCA1/2 families, and 47 geographically matched controls. Two polymorphisms were identified. SNPs $c.^*1287C$ >T (rs12516) (BRCA1) and $c.^*105A$ >C (rs15869) (BRCA2) were identified in 27% and 24% of patients, respectively. These 2 variants were also identified in controls with no family history of cancer (23.4% and 23.4%, respectively). In comparison to variations in the 3'UTR region of the BRCA1/2 genes and the BRCA1/2 mutational status in patients, there was a statistically significant relationship between the BRCA1 gene polymorphism $c.^*1287C$ >T (rs12516) and BRCA1 mutations (p=0.035) by Fisher's Exact Test. SNP $c.^*1287C$ >T (rs12516) of the BRCA1 gene may have potential use as a genetic marker of an increased risk of developing breast cancer and likely represents a non-coding sequence variation in BRCA1 that impacts BRCA1 function and leads to increased early-onset and/or familial breast cancer risk in the Turkish population.
Intravenous urography (IVU) for urolithiasis is a radiologic examination to diagnosis stone in the ureter path using iodine contrast media, which is radioopacity material. The method includes compression on the upper iliac crest. The compression band prevents outlet of the contrast media through the bladder and enables easier movement to upper urinary tract. This usage depends on the policy of a hospital. Therefore, this study aimed to review and compare the characteristic of progress of contrast media either in compression and non-compression. The retrospective image measurement on 60 cases of intravenous pyelography was conducted at a hospital with the identical type and amount of contrast media as well as criteria for testing. Image measurement was limited to 5 minutes clip, which is optimal for progress of contrast media depending on usage of the compression band. Also, anatomical regions were set as following: "RP" is from renal pyramid to renal pelvis, "PL" is from renal pelvis to lumbar three endplate, and "IU" and "IL" for upper and lower parts from both iliac crests. Analysis has been conducted through the statistical method based on Fisher's Exact Test to find if there are differences of distribution with the anatomical regions with compression or no compression. It has been confirmed that there is no statistical significant difference as the video measurement on 30 cases of compression and non-compression group respectively resulted in P value of 0.580 from left and 0.711 from right (both 0.960). Therefore, it has been concluded that application of a compression band on an intravenous pyelography for urolithiasis patient does not meaningfully affect the progress of contrast media.
Recently, various strengthening methods using carbon fiber sheets (CFS) have been developed for the rehabilitation of structures and applied to the concrete member. However, still research need arises in order to verify the structural capacity of RC member which experienced bond loss between concrete and CFS after strengthening. This is because previous research has focused on the development of design process and evaluation of structural capacity only for retrofit. The appearance of this loss may be initiated at just after retrofit construction. And it will be more serious when the layer number of CFS increases. In order to minimize above mistake in retrofit design using CFS, more exact evaluation process to predict the bond loss of CFS is required. The objective of this research is to study the variation of flexural structural capacity of beam which has experienced bond loss after strengthening using CFS. Experimental and analytical study are performed and evaluation of the previous formula is conducted. Test result showed that the significant strength deterioration was not found until the bond loss of 20%. Overall structural behavior of the beams can be predicted by nonlinear sectional analysis.
The purpose of the study is 1) to explore clinic and hospital CEOs' satisfaction and expectation level on the affiliation with the larger size teaching hospitals, 2) to find the factors influencing the satisfaction and expectation level on the affiliation with the large hospitals. Data for analysis was collected to use self-administrative structured questionnaire on 335 CEOs of small or middle sized clinics and hospitals affiliated with large sized teaching hospitals located in Seoul and Kyung Ki Province. For the study, the researchers develop the constructs for questions on the satisfaction and the expectation of the affiliation, the attitude, knowledge on the affiliation, previous relationship of the affiliation, and selection guideline of the affiliation with exploratory factor analysis and reliability test. Through the confirmative factor analysis using AMOS 4, the researchers develop constructs based on exact relationship between constructs and questions. CEOs' expressive and unexpressive satisfaction level are 2.54 of 5 point(38.5 of 100) and 2.78 of 5 point(44.5 of 100), and the expressive and unexpressive expectation level are 2.77 of 5 point(44.3) and 3.16 of 5 point(54.0). These levels are relatively row for importance of affiliation. Expectation levels do not influence satisfaction levels. Attitude of affiliation influences expressive expectation and unexpressive satisfaction, reason for affiliation unexpressive satisfaction, and previous relationship to affiliated hospitals influence both of expressive and unexpressive satisfaction. The expressive expectation level and the expressive satisfaction level influence unexpressive expectation and unexpressive satisfaction, respectively. There is cognitive dissonance between expectation and satisfaction, therefore numbers of affiliation might be smaller or weaker in the future than present time. Many CEOs feel environmental press such as competition and the press of health insurance, but they might not think affiliation is best solution. Therefore, large hospitals try to give affiliated clinics and hospitals practical benefits to increase satisfaction and expectation levels, and they need to new affiliation form such as joint venture and joint ownership. The expectation and the satisfaction level was influenced by CEOs' gender, type of health service facilities, distances between the affiliated facility and the large mother hospital, and reason for affiliation.
Fifty rice varieties were tested for alkali digestibility of milled rice grain at four different KOH levels, and twenty-four varieties selected were tested again for alkali digestibility at different degrading times and KOH levels. Gelatinization rate at several heating times and heating temperatures, and water absorption rate at 21$^{\circ}C$ and 77$^{\circ}C$ water temperatures were observed using rice samples of twenty-four varieties to clarify the relationship between alkali digestibility response, gelatinization rate and water absorption rate. Varietal difference of ADV in Japonica and Tongil tye rices was biggest at KOH 1.2%, but it was better to test at KOH 1.2% and 1.4% levels to know the exact alkali digestibility response of rice varieties. Rice varieties tested could be classified into three groups, low, intermediate and high, based on their alkali digestibility response at four KOH levels, and most of Korean cultivated rice varieties were belonged to intermediate or high ADV group. Varietal variation was also found in alkali degrading response at different soaking times in alkali solution. Low ADV varietal group showed higher gelatinization temperature and needed longer heating time for complete gelatinization compared with intermediate or high ADV group. Same trends was found between intermediate and high ADV groups, but varietal variation in the same ADV group was also found in gelatinization temperature and heating time needed for complete gelatinization of rice grain. Water absorption rate of low ADV group was lower than intermediate or high ADV group both at 21$^{\circ}C$ and 77$^{\circ}C$ water temperatures, and intermediate ADV group showed lower absorption rate than high ADV group only in initial water absorption stage at 21$^{\circ}C$.

Efficient pollination needs abundant fertile pollen in rose breeding. This study was performed to find out efficient staining methods for the detection of fertile pollen. Aceto-carmine and Alexander's stain gave similar results in terms of percentage of normal pollen. Fluorochromatic reaction (FCR) showed the lowest normal pollen percentage because FCR stained only fertile pollen while others stained cytoplasm. Toluidine blue O (TB) showed similar percentage of normal pollen to Aceto-carmine and Alexander's, but could not clearly distinguish the clustered abnormal pollens. Alexander's stain was easy and simple, but difficult to distinguish fertile and infertile pollen. FCR showed only fertile pollen. Alexander's stain showed approximate fertility and FCR showed exact pollen fertility.
It requires professional knowledge and much time to judge intellectual property rights infringement. The duties of customs administration are the balance between the propositon of trade facilitation through rapid clearance and the thesis of social security through exact examination. There is a view that the criminal procedure law control is necessary to the goods inspection of clearnce procedure if it is related to crimianl investigation. However, it seems that the customs law does not consider the goods inspection investigation as the investigation under judicial control, but only the mere administrative investigation. It can be said that the inspection of goods by customs law functioning as a clue of investigation is confined to the ordinary goods inspection, including the screening test. Searching for specific articles by specific informaition should be under the control of criminal procedure law because it constitutes the commencement of criminal investigation in criminal cases. This interpretation could be an opportunity as a harmonious operation between the goods inspection of customs clearance and the search and seizure of criminal procedure.

Purpose: This study evaluated the prognosis of conservative and surgical treatment according to the staging of bisphosphonate-related osteonecrosis of jaw (BRONJ) by American Association of Oral and Maxillofacial Surgeons and American Society for Bone and Mineral Research. Methods: We evaluated 53 patients of BRONJ who visited Department of Dentistry, Ajou University School of Medicine from May 2007 to February 2013. Twenty eight patients in stage 2, were divided into surgical and conservative groups with cessation of bisphosphonate therapy. Fifteen patients belonged to the conservative treatment group, in which mouth rinsing and antibiotics medication were done. Thirteen patients were treated with debridement or sequestrectomy, in the surgical treatment group. Each study list was analyzed by SPSS ver. 14.0 (SPSS Inc., USA) software and the favorable rate was verified by the Fisher exact test. P-values less than 0.05% were deemed significant. Results: Clinical outcome was evaluated on the basis of both clinical and radiographic findings. Of all the 28 patients of stage 2, 15 patients underwent conservative treatment and 13 patients received surgical treatment. In the surgical group, 9 of 13 (69.2%) showed good prognosis, 4 of 13 (30.7%) showed recurrence. In the conservative group, 13 of 15 (86.6%) showed no change duting the follow-up period. Two of 15 patients even showed a bad prognosis, such as pain and pus discharge, which are criteria for stage 3. P-value was 0.067 (>0.05). Conclusion: The results of the present study suggests that surgical intervention is good choice against the conservative treatment, after proper drug holidays period, while further investigation is needed for a definite solution to BRONJ.
